水平冷凝管中分相流的传热

Heat Transfer Investigation of the Stratified Two-Phase Flow in Horizontal Tubes

本文对饱和蒸汽流经水平冷凝管时汽－液分相流的流动和传热模型进行了讨论，并给出有关方程。用该模型对饱和氨蒸汽流经水平铝管时的传热特性进行了计算，给出了流动参数和热学参数的轴向分布，并考察了有关因素对诸参数分布的影响。

The physical model and calculation motheds for the stratified two-phase flow in a horizontal condensation tube are investigated in this paper. The action of gravity and the effect of mass transfer on the interfacial shear are considered in this model.The program were used to calculate the flow and heat transfer characteristics of NH3-Al horizontal condensation tube and to give the axial profiles of parameters. The effects of flow rates and cooling conditions on this profiles were examined.
